Lord Of The Rings star Sir Ian McKellen was offended on live TV – when he was confused with another big-screen wizard and was asked about his role in Harry Potter. The legendary British actor was appearing on US TV's The View, when actress and host Whoopi Goldberg, asked: "Now, are you coming back in Harry Potter?" Sir Ian looked clearly annoyed as he closed his eyes and paused before answering. As Goldberg began to look uncomfortable and confused by his response, Sir Ian said: "Well, if I were Mike Gambon, I might, but I don't play Harry Potter, I don't play Dumbledore – I play Lord Of The Rings, darling." As the audience gasped at her mistake, the Sister Act star sheepishly shook her head and repeatedly said, "I'm sorry" and "I know better". Sir Ian finally chuckled and reached over and patted her knee. "You're not the only one to make that mistake," he told her. "One wizard is much like another."
